4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler.
4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports over 85% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, recursion, include files, etc.
It comes with an RPN calculator, line editor, compiler, decompiler, C-source generators, and a virtual machine.
